PURPOSE: To report the results of acetabular revisions performed with the cementless, hemi-spherical porous coated component supported by viable host bone and minimal allobone graft for acetabular deficiencies. MATERIALS AND METHODS: A retrospective study was completed for 22-revision acetabular components, using the cementless hemispherical porous coated prosthesis and minimal femoral head allograft. There was an average follow up of 48 months, with a range of 24 to 84 months. Radiographic measurements were performed in several aspects; cup-allograft contact, inclination, vertical and horizontal migration of acetabular cup, and acetabular zone by modified zone of DeLee and Charnley, in which location, size and progression or non-progression of radiolucent zone were recorded. The acetabular deficiencies were classified by the American Academy of Orthopaedic Surgeons Committee and were type I in 2 hips (9%), type II in 12 hips (55%), and type III in 8 hips (36%). Twenty acetabular cup cases of Harris-Galante II were used in this study, 1 case of Harris- Galante I, and 1 case of Duraloc. The average size of the cup was 57(44-66) mm. RESULTS: The average cup-allograft contact was 72.5% in 19 cases and we could not differentiate the margin between the host bone and the allograft in 3 cases. There was no significant vertical or horizontal migration of acetabular cup. Radiolucent zones in follow-up radiographs were 8 cases in zone IA, 4 cases in zone IB, 4 cases in zone IIB, 9 cases in zone IIC, 8 cases in zone IIIA, and 7 cases in zone IIIB. One case showed 2 mm radiolucent area in zone IIC and another case showed 3 mm radiolucent area in zone IIB, but the radiolucencies were not progressive. The remaining cases showed less than 0.5 mm radiolucent area or no radiolucent zone. The average period of bony incorporation was 13.1 months. CONCLUSIONS: We suppose that acetabular revision with the cementless hemispherical porous coated cup supported by viable host bone and minimal bone graft produces good results.

A preliminary study was conducted to evaluate the immediate postoperative recovery and socioeconomic efficacy with the surgical release of Carpal tunnel syndrome by double incision technique. Sixty cases of carpal tunnel syndrome were operated by one surgeon between 1993 and 1995 and 44 cases in 39 patients were available for this study. Surgery was done under axillary block and patients were evaiuated preoperatively, 3 weeks and 6 weeks each postoperatively. The evaluation was focused on the immediate recovery in terms of subjective symptoms of pain and paresthesia, local tenderness, strength of grip power and pinch power and postoperative disability. 1l was noted that surgical release of carpal tunnel syndrome utilizing double incision technique was as effective as seen in the endoscopic release in terms of quicker recovery of pain, local tenderness and strength. It was also noted that this double incision technique was as safe and economically beneficial as observed in the conventional open procedure.

Recent advances in surgical techniques and equipment have made bone lengthening by callotasis both easier and safer, and many successful clinical cases have been reported. The callus formation, however, has often been very poor, and prolonged applied of the external jixator increases the risk of serious complications, such as pin tract infection. We reviewed 68 cases of limb lengthenings performed with callus distraction in 48 patients at Kang Nam St. Mary' s Hospital between January 1989 and May 1994. There were 29 female and 19 male patients, with an average age of 19 (6-50) years. Causes of limb shortening were short stature (14), poliomyelitis (8), fracture and physeal damage (6), osteomyelitis (6), Legg-Calve-Perthe's disease (4), bone tumor (3), congenital dislocation of the hip (3), leg length discrepancy (3), achondroplasia (2) and hip dysplasia (1). Sixty eight calluses were classified radiographically into 6 types: external, straight, attenuated, opposite, pillar, and scattered. The healing indexes and complications following the procedure were evaluated. The mean femoral lengthening was 6.2 (2-10) cm, the tibial 6.5 (3.3-15.7) cm, the forearm 1.8 (1.6- 2.2) cm and the humerus 10 cm. Fifteen cases classified as external type, 5 femur, 7 tibiae, 2 forearm and 1 humerus, with healing index of 34 days/cm and no major complications. Thirty one cases classified as straight type, 7 femur, 22 tibiae, 1 forearm and 1 humerus with healing index of 38 days/cm and 2 obstacles. Fourteen cases classified as attenuated type, 4 femur and 10 tibiae with healing index of 47 days/cm and 2 obstacles. Six cases classified as opposite type, 4 femur and 2 tibiae with healing index of 65 days/cm and 3 obstacles and 1 residual complications. Two cases classified as scattered type, 2 tibiae with healing index of 116 days/cm and 5 obstacles. The scattered type of the callus in two cases was suspected to be a result of poor callus formation due to K-wire breakage conditions that autogenous bone marrow transplantations were performed. This classification enabled us to estimate the intrinsic conditions, predict the healing index, incidence of complications, and decide to apply early bone marrow injection to the callus.

Peritendinous adhesions which develop in the flexor tendons of the digits after injury or operation are still a major problem in the surgery of the hand. The adhesions that are part of the healing process constitute an almost inevitable functional disability during the biological response of the tissue to injury. To achive better gliding function of flexor tendons, continuous efforts are being made to reduce peritendinous adhesions without adversely affecting the healing process itself. To reduce peritendinous adhesions, an aqueous solution of beta-aminopropionitrile (BAPN) was added to a solution of enriched native collagen (E.C.S.) and applied to the cut tendons of one group: untreated controls and controls treated with collagen solution alone comprised the other groups. Chickens from each group were sacrificed one, three and five weeks after operation. Tn he results were evaluated grossly and pathologically. The results of this experiment were as follows. 1. The collagen solution alone had the same lathylogenic effect as the beta-aminopropionitrile. 2. There were no systemic complications with beta-aminopropionitrile. 3. The beta-aminopropionitrile collagen solutions had the adverse effect on the tendon healings.

Paragonimus westermani mainly infests the lung parenchyma, and it is also causes ectopic parasitism of various sites, such as brain, liver and subcutaneous tissue but there have been no reports in literature about paragonimiasis infesting lumbar epidural space. A 58-year-old housewife complained of lumbago and radiating pain to both lower extremities for 20 years. Calcified extradural masses were found by preoperative plain X-ray, myelogram, and CT scan. Intraoperatively, cystic mass in the epidural space at L2-3 was found and confirmed to be paragonimiasis by histopathological study. A case of ectopic paragonimiasis in the lumbar epidural space at L2-3 level is presented.
